Pyrolysis has many applications in food preparation. [23] Caramelization is the pyrolysis of sugars in food (often after the sugars have been produced by the breakdown of polysaccharides). The food goes brown and changes flavor. The distinctive flavors are used in many dishes; for instance, caramelized onion is used in French onion soup.
Pyrolysis or thermal decomposition of wood in a low oxygen manner originated prehistorically to produce charcoal. Condensates of the vapors eventually were made and found useful as preservatives. For centuries, water-based condensates of wood smoke were popularly called "wood vinegar", presumably due to its use as food vinegar.
Pyrolysis oil, sometimes also known as biocrude or bio-oil, is a synthetic fuel with few industrial application and under investigation as substitute for petroleum.It is obtained by heating dried biomass without oxygen in a reactor at a temperature of about 500 °C (900 °F) with subsequent cooling, separation from the aqueous phase and other processes.
In 1895, pyroligneous acid was first marketed under the brand Wright's Liquid Smoke, [8] a liquid smoke product intended to impart the flavor and some of the preservative effects of wood smoking to meats and vegetables. In the early 21st century, concerns about the carcinogenic effects of components of wood smoke decreased the production of ...
This process is known as pyrolysis. Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. [1] Mineral products resembling tar can be produced from fossil hydrocarbons, such as petroleum.

Smoke deposits a number of pyrolysis products onto the food, including the phenols syringol, guaiacol and catechol. [9] Salt accelerates the drying process using osmosis and also inhibits the growth of several common strains of bacteria. More recently nitrites have been used to cure meat, contributing a characteristic pink colour. [10]
C5 sugars (e.g., xylose, arabinose: C 5 H 10 O 5), from hydrolysis of hemicellulose and food and feed side streams; Lignin from the processing of lignocellulosic biomass. Liquid from pyrolysis (pyrolysis oil) Products: Biorefineries can be grouped in two main categories according to the conversion of biomass in an energetic or non-energetic ...
